Required Apache modules:

• rewrite
• headers
• proxy_http
• proxy_fcgi
• proxy_wstunnel

 

The Apache2 virtual hosting configuration,

/etc/apache2/sites-available/01-drupal8.conf

- created by the Ansible playbook from template - is the following:

 
<virtualhost>

        ServerName test.ip6m.net

        ServerAdmin info@ip6m.net
        DocumentRoot /var/www/drupal8/web

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        <directory drupal8="" var="" www="">;
                AllowOverride All
                SetEnvIf Origin "http(s)?://(mobile\.)?(test.ip6m.net|localhost:8080)$" AccessControlAllowOrigin=$0
                Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
                Header add Access-Control-Allow-Credentials true
                Header add Access-Control-Allow-Headers "x-csrf-token, authorization, content-type, accept, origin, x-requested-with, access-control-allow-origin, x-allowed-header, *"
                Header add Access-Control-Allow-Methods: *
        </directory>;

        RewriteEngine On

        RewriteCond %{REQUEST_URI}  ^/socket.io            [NC]
        RewriteCond %{QUERY_STRING} transport=websocket    [NC]
        RewriteRule /(.*)           ws://localhost:8082/$1 [P,L]

        ProxyPass        /socket.io  http://localhost:8082/socket.io
        ProxyPassReverse /socket.io  http://localhost:8082/socket.io

</virtualhost>

The following section works as reverse http proxy that separates the Drupal http and the NodeJS server's websocket traffic:

 
       RewriteEngine On

        RewriteCond %{REQUEST_URI}  ^/socket.io            [NC]
        RewriteCond %{QUERY_STRING} transport=websocket    [NC]
        RewriteRule /(.*)           ws://localhost:8082/$1 [P,L]

        ProxyPass        /socket.io  http://localhost:8082/socket.io
        ProxyPassReverse /socket.io  http://localhost:8082/socket.io

The SSL version of the configuration has the following additional lines, expecting that a Letsencrypt https certicifated is installed:

 
SSLEngine on
SSLCertificateFile      /etc/letsencrypt/live/test.ip6m.net/fullchain.pem
SSLCertificateKeyFile   /etc/letsencrypt/live/test.ip6m.net/privkey.pem

The required PHP version for Drupal 8 is 7.2.

The required modules:

• php-mysql
• php-fpm
• php-xml
• php-mbstring
• php-gd
• php7.2-xml
• php-curl

 

The IP6M installer playbook installs and configure php-fpm (FastCGI Process Manager) for higher performance and optimal memory usage.
